Patent CA-2304878-C (CA)
Inventor: MANN SAMUEL J
IPC: A44C7/00

Granted: 2008-08-26
Abstract: A disposable Ear Piercing device consists of an outer cartridge which is inserted into the piercing instrument. The outer cartridge contains a slideable inner capsule retaining an earring with a slideable spacer therein. By applying force to the instrument handle, an internal driving rod advances the inner capsule and slideable spacer forward, forcing the earring post through the ear and into a closed bottom retaining clutch. At such time, the earring is released from the inner capsule by spring arms which are integral with the spacer, opening hinged doors or door on the inner capsule, clearing the outer cartridge and allowing the earring and clutch to be released from the capsule onto the ear. The design of such inner capsule and spacer allows unsymmetrical decorative heads of varying thickness to be utilized.

Filed: 2000-09-06
Granted: 2005-08-16
Abstract: When an image having an aspect ratio of 16:9 is compressed in a vertical direction to be displayed on a display screen having an aspect ratio of 4:3, a gray scale signal is inserted into a top and a bottom of an image signal and a brightness level of the inserted gray scale signal is made to correspond to an average brightness level of the image signal. In addition, when an image having an aspect ratio of 4:3 is compressed in a horizontal direction to be displayed on a display screen having an aspect ratio of 16:9, a gray scale signal is inserted into a right edge and a left edge of an image signal and a brightness level of the inserted gray scale signal is made to correspond to an average brightness level of the image signal. Accordingly, a boundary line between a video image area and a non-video image area due to the difference in luminous characteristics of phosphors becomes hardly recognizable.

Title: Method and device for determining the filling level in containers
Inventor: HEUFT BERNHARD
IPC: G01F23/28
Filed: 1999-04-27
Granted: 2010-07-06
Abstract: In order to determine the filling level in containers, mechanical vibrations are generated in the wall of a container (30) and the course of said vibrations is analyzed. The wall of a container in which the vibration is produced is touched at a different distance according to filling level. The vibration pattern is subsequently evaluated according to the distance at which the inside of the container wall (30) is touched. It is thus possible to determine the relaxation time, frequency, intensity and/or the time integral of the intensity or the point of maximum intensity of the mechanical vibrations in the container wall.

Abstract: A method for heat-treating metallic workpieces, in which a flow of cooling gas is generated in a vacuum furnace by a fan in order to quench the workpieces, with the fan being driven by a rotary current motor that is operated with a predetermined supply voltage above a minimum pressure in the vacuum furnace which is determined with regard to the motor power of the rotary current motor. In order to additionally develop this method such that a simple and inexpensive improvement of the quenching effect is achieved, the fan is started at a pressure in the vacuum furnace which is lower than the minimum pressure, with the rotary current motor being operated with a second, lower supply voltage until the minimum pressure in the vacuum furnace is reached.

Les premiers dispositifs de décision par phase reçoivent et choisissent parmi un certain nombres d'exemples d'un signal (A1-A16, B1-B16), ce qui produit des premiers signaux correspondants choisis par phase (C1, C2), et le second dispositif de décision par phase fonctionne pour recevoir et choisir parmi les premiers signaux choisis par phase, ce qui produit un second signal choisi par phase. Selon des modes de réalisation différents, les premiers dispositifs de décision par phase déterminent (220) indépendamment des temps de conclusion de décision (TA, TB) qui ne coïncident pas généralement, ou qui déterminent indépendamment (420) des temps de conclusion de décision (TAB, TAB') qui coïncident pratiquement, ou encore un des premiers dispositifs de décision par phase détermine (320) un moment de conclusion de décision commun (TAB) qui est communiqué (325) aux autres premiers dispositifs de décision par phase. Les moments de conclusion de décision respectifs déterminent le moment auquel les premiers signaux choisis par phase sont envoyés au second dispositif de décision par phase. Selon un autre mode de réalisation, les premiers dispositifs de décision par phase reçoivent (500, 540) plusieurs exemples d'un signal, extraient des informations caractéristiques, y compris, par exemple, des informations de groupes de contexte (545) et un statut d'erreurs (555) et déterminent le caractère d'acceptation des signaux par détermination par exemple, du contexte approprié (550) des signaux et du meilleur statut d'erreurs (560) de ceux-ci par rapport à un seuil d'erreur prédéterminé. Puis, les exemples du signal à critères d'acceptation positifs peuvent être envoyés à un second dispositif de décision par phase.
